Question

我在Linux Mint 13 Maya上使用Netbeans 7.4。我学习了如何编写一个简单的JSF复合组件。但我有一些错误：

当我尝试启动我的应用时：

<my_composite_component:register> Tag Library supports namespace: http://java.sun.com/jsf/composite/my_composite_component, but no tag was defined for name: register

当我尝试使用我的组件时：

“No library found for namespace http://java.sun.com/jsf/composite/my_composite_component”

继承我的Netbeans项目中的目录结构：

和代码：

register.xhtml - 我的复合组件

            <h:message for="textPanel" style="color:red;" />

            <h:panelGrid columns="2" id="textPanel">

                #{cc.attrs.nameLable} : 
                <h:inputText id="name" value="#{cc.attrs.nameValue}" />

                #{cc.attrs.emailLable} :

Answer 1

我正在使用jsf 2.2而不是java.sun.com/jsf，我将其用作命名空间：

xmlns:my_composite_component="http://xmlns.jcp.org/jsf/composite/my_composite_component

NETBEANS 7.4：“没有为name定义标记：register”+“找不到名称空间http://java.sun.com/jsf/composite/my_composite_component的库”
